I'm curious to hear more about why that would be the case. Money swaps hands constantly and we have explicit ways that a single dollar can become many multiples of itself (aka you get a dollar, you put it in a bank, the bank lends me 90 cents, I put it in a different bank, they lend you 81 cents, one of us gets another loan secured by our assets, etc, etc, etc, now how many dollars are there?).
